Hello all in a project with an MSP430 I have to print to an IRDA-Printer and to send/receive Konfiguration data to/from a PDA At least I decided to use the IRDA stack from Embednet. Does anybody use it and could tell me about its reliability and/or problems? What's about the support of embednet, any experiences? TIA Holger

I am trying to port the JTAG library released with TI App. Note 149 for use with my parallel port. I am able to reset the device and perform basic initialization over JTAG. However, I am having problems with writing to on-chip RAM. It turns out that whenever I write to a location, the location last accessed (read or write) gets corrupted. Here's an output showing what I mean: -------------...

Greetings, Is there a way I can perform a hardware test on a S1D13705 Epson LCD Controller. I am currently interfacing the controller with an MSP430, using various ports to access the Controller, my current test code isn't working, but there is no way of finding out if the chip, or my code is at fault. Any help would be appreciated. Elfred

Hi all, I've been looking into how to interface huge and cheap consumer flash memory cards with hobby projects powered by an AVR, PIC, or MSP430. A lot of the advice seems to be to use MMC or SD memory cards in SPI I/O mode. That seems like a good approach, but (1) sockets for these cards might be hard for a new hobbyist like me to solder, and (2) I already have a bunch of CompactF...

Hi All, What is TI talking about when they refer to the floating point package(FPP)? Is is able to be used on any of their uC? I need the uC to take the square root of a number and it seems that I'll have to use the FPP to do it. Is that true? What is the FPP used for? Thanks David

I know that I've seen a TI document about this before, but a 15 minute google search left me with nothing. I am double-checking a schematic that uses an MSP430F149, and I want to ensure that I have all the pins correctly terminated for (1) correct operations and (2) access to the JTAG port for in-circuit programming and debugging. Here's what I've got: AVcc -- 3.3V DVcc -- 3.3V DV...

Hi all, Spin time... I've tested out enough of my sub electronics to be able to start optimizing. I'm contemplating the MSP430F149 or F135 as a candidate to replace a few 8-bit micros [that are currently way under-utilized anyway]. This is a dual-purpose project; saving power and also learning the MSP430 as I will be using it extensively in the coming years at work. However, at home I w...

Hi! I have to program a MSP430F11(0/1)1 (1/2KB Flash, 128B RAM) to do 2 tasks: - RX/TX bus connection - measure a capacitance with timer_A The measurement has to run every certain time. But this has not the highest priority. It is better for me to loose one measurement cycle and therefore get incoming bus data. At this point I remark, that I can't adjust interrupt priorities in the ...
